Abstract
Соединительный элемент для соединения внутрискважинных труб содержит трубчатый корпус и по меньшей мере одно из следующего: охватываемую винтовую резьбу, выполненную на наружной поверхности указанного корпуса, и охватывающую винтовую резьбу, выполненную на внутренней поверхности указанного корпуса. Указанная по меньшей мере одна резьба имеет профиль, содержащий выступ, впадину и пару боковых поверхностей. Выступ и впадина изогнуты вокруг соответствующего первого и второго радиусов изгиба. Каждый радиус изгиба больше наружного диаметра соединительного элемента.A connecting element for connecting downhole pipes comprises a tubular body and at least one of the following: a male screw thread made on the outer surface of the said body and a female screw thread made on the inner surface of said body. The specified at least one thread has a profile containing a protrusion, a depression and a pair of side surfaces. The protrusion and trough are curved around the respective first and second bend radii. Each bend radius is greater than the outer diameter of the connector.
